ILLUMINATED SIGN.

Specification of Letters Patent.

Patented Aug. 4, 1914.

Application filed May 14, 1913. Serial No. 767,507.

To all whom it may concern:

Be it known that I, JOHN L. DAWES, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Illuminated Signs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- I Figure 1 is a side elevation partly broken away, embodying my invention; Fig. 2 is a detail sectional view on the line IIII of Fig; 1; Fig. 3 is a side elevation showings modification; and Fig. 4: is a detail view in perspective of a portion of the ring and splice plate.

My invention relates to illuminated signs for advertising purposes, and is designed to provide a device of this character which is cheap, simple and effective and may be made at low cost with a single ring supporting both glass sides.

In the drawings, 2 represents the surrounding band or ring which is preferably formed in the cross sectional shape shown in Fig. 2, by drawing or any other desirable manner. The band is then bent around into the desired shape, here shown as circular, and its abuttingends are secured together in any desirable manner, as, for example, by the single splice plate 3, which may be soldered, riveted, or otherwise secured to the end portions.

At each side of the ring is an inwardly projecting seat 4, to receive the edge of the glass plate, and outside of this seat is another seat 5, to receive the spring wire ring 6, which holds the glass plate in place. Both sides are alike, and the members are assembled by simply dropping the glass plate into Copies of this patent may be obtained for five cents each, by addressing the Commissioner 0! Patents,

place against its seat and then springing the wire ring into its seat. The spring wire is preferably provided at one end with a loop or hook 6, which facilitates its insertion and removal.

At one side the ring is provided with a hole, within which is secured the stem 7, of the electric light 8. This may be secured by inner and outer hubs 9 or in any other desirable way. The metal ring is provided with ventilating holes, such as shown at 10.

The advantages of my inventionresult from the simplicity, cheapness and effectiveness of the design. As the rim is made in one piece and the glass plates are secured by spring rings, the device may be cheaply made and easily removed and taken apart. I have shown the glass plates as of convex form, projecting outwardly, but they may be of any desired shape or form. The sign may be of circular shape or any other desired shape.

I claim:

A sign structure comprising a single surrounding band of sheet metal having its ends secured together, the band having circumferential crimped portions at each side,

flanges projecting outwardly beyond the crunped portions at each side, and having internal ring seats, translucent plates at each side engaging the crimped portions, and spring rings removably engaging the ring seats to hold the translucent plates, said plates being removable outwardly from each side face, substantially as described.

In testimony whereof, I have hereunto set my hand.
